Standardized Anodize Coating Tests

Registered Visitor

We extrude, fabricate and anodize as a tier 2 to the automotive sector. Anodize test were pretty basic in that if you passed color / seal / appearance all was good. With new ventures comes additional testing requirements. What I am wondering is if anyone knows of one specific series of test that I can have done versus a bunch of different ones that would satisfy all the different anodize specs the automakers have? Parts in question are clear or black interior components. My goal is to do outside lab testing once a year to augment the daily in house testing.

I found this listing of common tests. However, you will always have to deal with some customer specific tests (e.g., GMC vs. Ford corrosion tests). Others such as weatherometer and fadometer are more likely to be standard.

It depends on customer requirements. I find that most, if not all, anodize standards will come with periodic process control testing that's required to validate the process. Either that or they will reference other standards.
